The efficiency of using the multicaloric effect (μCE) in solid-state cooling systems is investigated and compared with single caloric effects. The proposed approach is illustrated by the example of the Brighton cycle for μCE and the magnetocaloric effect. Based on the conducted experiments for the two-layer composite Fe48Rh52–PbZr0.53Ti0.47O3, the dependence of relative efficiency on temperature is constructed and the temperature range is estimated, where μCE has an advantage over the magnetocaloric effect. The comparison of the developed theory of the μCE with the obtained experimental data is performed.
